1// Source: https://www.w3.org/TR/wai-aria-1.1/#roles2/* easiest way to see allowed roles is to filter out the global ones3 from the list of inherited states and properties. The dpub spec4 does not have the global list so you'll need to copy over from5 the wai-aria one:6 const globalAttrs = Array.from(7 document.querySelectorAll('#global_states li')8 ).map(li => li.textContent.replace(/\s*\(.*\)/, ''));9 const globalRoleAttrs = Array.from(10 document.querySelectorAll('.role-inherited li')11 ).filter(li => globalAttrs.includes(li.textContent.replace(/\s*\(.*\)/, '')))12 globalRoleAttrs.forEach(li => li.style.display = 'none');13*/14const ariaRoles = {15 alert: {16 type: 'widget',17 allowedAttrs:
